(01. 1581-92) Thisinvention relates to improvements "in liquid fuel burners'andparticularly one of the heater type, although adaptable to'otherinstallations. Y i

The use of fuel oil for heating has rapidly become more extensive andmany devices have been placed on the market attempting to,- over-' comecertain difliculties'whichhave limite'dfthe wider acceptance of liquidfuel spite of its many conveniences. The most serious of thesedifiiculties is the need of reducing 'theffuel COIL-5 sumption and thenoiseqof combustion ofthe burner in operation. f Y

My present invention has for its mainpbje'ct the provision of a liquidfuel burner that is "ex-.1 tremely economical in operation regardless ofthe grade of fuel oil usedlfiWhile economy in'such'fa burner isbestevidencedby the reduction of fuel consumption, it is also wellrepresented by other advantages which my invention affords, such as,freedom from carbonization and quietnessof op eration, permittingsafeand efficient use; I

I am able to effect these economies by providing a burner in which thefuelwill be thoroughly vaporized, and mixed with air and water vapor andthoroughly burne'dwiththe heatlfof com bustion evenly distributedupwardly and fout-' wardly as a flaringsheet of flame.

I am aware of t e fact that ttemptsl'have' been made to utilizea steamgenerator .to vapor-.

My invention is capable. of installation in any fire box and, ofcoursej'standard ignition and control equipment may be used; These have,however, been. omitted from the drawing and specification in whichIjhave shown, and described a simple embodimentof my invention showingonly such controls asfare necessary. for absolute safety.

An oil burner constructed in accordance with my invention may be easilyinstalled in any fire boxl as it is supported by a,base 2 through whichare threaded the adjustable legs 3-to permitj proper levelling of the,unitlon the furnace fioor 4. The space between the top of theburnerandthe wallof the fire box is preferably sealed as by the'plate 5anchored in or to the wall ,6 of the ire box 1 as at '7 and preferablymade tight with asbestos or like cement as indicated at The base 2 isprovided with an upright 9 onto which the bowlB is threaded. The bowlconsists of a heavier bottom member 10 and a relatively thin; lighterside 'wall ll which secured to. the mouth 10 of the member i0; wlqiich-has an external'iiange'12for that"'pur'posel "A rim plate 3 overhangstheopenend of the wall 11 and contactsfth'e platebi;

"The delivery end ofthe pipe i4 is surrounded bythe axial" core 17 which is mounted on the annular shoulder l8t on themember 10; The

core 17 provided'with'a plurality or apertures 19 in'itslower pqrtionto'permit the, passage of thefoil into the"lojovvl' 1O whe'rejit isvaporized. The core '17 serves aI SOQQS a supportjfor the baflie plate20 whichsubstantially overhangs the space between theicor'eTl'liandithe' rim plate 13.
